Definitions

  • the present invention relates to medical infusion apparatus such as used for administering an infusion liquid intravenously to a subject.
  • the invention relates in particular to a safety valve included in such infusion apparatus.
  • medical infusion apparatus comprising: a container for a liquid to be infused; tubing leading from the container to the subject to receive an infusion; a pump for pumping the infusion liquid via the tubing to the subject; and a safety valve connected to the tubing between the pump and the subject; the safety valve being normally closed to prevent free-flow of the liquid from the container but being automatically opened when a predetermined minimum pressure is applied to the liquid by the pump, the safety valve being characterized by comprising a cannula (20) having an axial passageway (21) from one end of the cannula but closed at the opposite end, and a radial bore (23) adjacent said opposite end leading from said axial passageway to the outer surface of the cannula; and an elastomeric sleeve (24) around the cannula and overlying and normally closing said radial bore, said safety valve also being manually deformable e.g., by squeezing, bending or twisting.
  • Medical infusion apparatus equipped with such a safety valve normally blocks the flow of the infusion liquid, thereby preventing infusion liquid from being gravity-fed to the patient should the pump be disconnected.
  • a safety valve is automatically opened by a predetermined minimum liquid pressure as applied by the pump. It may also be manually opened by manually deforming (e.g., squeezing, bending or twisting) it to permit priming the apparatus.
  • Such apparatus thus provides protection against the above-mentioned danger of inadvertently feeding infusion liquid to the patient when the pump is disconnected, and also enables the apparatus to be primed in a convenient manner.
  • safety valve 10 may also be manually opened by manually squeezing it to permit priming the apparatus, i.e., purging it of air.
  • cannula 20 One end of cannula 20 is formed with an annular seat 26 for receiving tube 11, and its opposite end is formed with another annular seat 27 for receiving tube 12, whereby the cannula connects together the two tubes 11, 12, with the safety valve in between.
  • the cannula 20 and the overlying sleeve 24 may be squeezed together to open the radial bores 23 in order to permit manual priming of the apparatus before connecting it to the pump.
  • squeezing the opposite sides of the sleeve 24 will deform it into an elliptical shape and will cause the portions of the sleeve not engaged by the user's fingers to move outwardly away from the outer surface of the cannula to thereby uncover the respective radial bores 23.
  • This opening of the radial bores to permit manual priming of the apparatus would be further enhanced by making the cannula 20 also deformable by this squeezing pressure.

Claims (4)

  1. Medizinischer Infusionsapparat, umfassend: einen Behälter (3) für eine zu infundierende Flüssigkeit; Schlauchleitung (4), die von dem Behälter zu dem Patienten führt, der eine Infusion erhält; eine Pumpe (6) zum Pumpen der Infusionsflüssigkeit über die Schlauchleitung zu dem Patienten; und ein Sicherheitsventil (10), das mit der Schlauchleitung verbunden ist, und sich zwischen der Pumpe und dem Patienten befindet; wobei das Sicherheitsventil normalerweise geschlossen ist, um ein freies Strömen der Flüssigkeit von dem Behälter zu verhindern, das jedoch automatisch geöffnet wird, wenn ein vorbestimmter Mindestdruck von der Pumpe auf die Flüssigkeit gegeben wird; dadurch gekennzeichnet, dass das Sicherheitsventil eine Kanüle 20 aufweist, die von dem einen Ende der Kanüle einen axialen Durchgang (21) hat und an dem gegenüberliegenden Ende geschlossen ist, sowie eine radiale Bohrung (23), angrenzend an dem gegenüberliegenden Ende hat, die von dem axialen Durchgang zu der Außenseite der Kanüle führt; sowie eine elastomere Manschette (24) um die Kanüle und über der radialen Bohrung sitzt und diese normalerweise geschlossen hält; wobei das Sicherheitsventil auch manuell deformiert werden kann, z.B. durch Drücken, Biegen oder Verdrillen, um das Ventil zu öffnen und ein Ansaugen des Apparates zu ermöglichen, indem dieser mit Luft gespült wird.
  2. Apparat nach Anspruch 1, dadurch gekennzeichnet, dass in die Kanüle eine kreisrunde Befestigungsfläche (26, 27) an beiden Enden zur Aufnahme der Schlauchleitung einbezogen ist, um die zwei Abschnitte (11, 12) der Schlauchleitung zusammen mit dem Sicherheitsventil dazwischen zu verbinden.
  3. Apparat nach Anspruch 1, dadurch gekennzeichnet, dass die Außenseite des gegenüberliegenden Endes der Kanüle mit einer Rippenbildung (25) zur Anbringung der elastomeren Muffe versehen ist.
  4. Apparat nach Anspruch 1, dadurch gekennzeichnet, dass zwischen der Außenseite der Kanüle und der Innenseite der elastomeren Muffe ein Gleitmittel aufgetragen wird.
